"WILLIAM KANE, OF PHILADELPHIA, PENNSYLVANIA.

AUTOMATIC REGULATOR.

Specification of Letters Patent.

Patented June 2, 1914.

Original application filed August 1'7, 1912, Serial No. 715,529. Divided and this application filed November To all whom it may concern: Be it known that I, VVlLLIAM KANE,'c1t1- zen of the United States, and resident of .hot water to a water system wherebythe heat is supplied to the water commensurately with the requirements, more or less instantaneously, upon inducing a flow by opening of a hot water spigot or spigots in the house supply system.

It has for a further object to provide antomatic means which will insurethe boiler remaining substantially full of water, to the exclusion of material quantities of steam, and in which the pressure conditions I within the boiler shall automatically govern the supply of heating medium, so that, while at no time can the boiler and its contents become overheated to cause the gen eration of steam, a proper heating of the water therein is insured the moment that the pressure within the boiler is reduced by drawing water therefrom by the turning on of a spigot or spigots in the house supply system.

My invention consists of certain featu res of construction which are fully described herematter, and more particularly defined in the claims. a

The invention will be better understood by reference to the drawings, in which Figure 1 represents an elevation of a hot water boiler system embodying the automatic regulator of my invention; Fig, 2 is a. transverse section of the same taken on line cc-w of Fig. 1; and Fig. 3 is a sectional elevation of the regulator embodying myinvention.

Similar numerals of reference indicate corresponding parts.

1 designates an upright boiler body of any suitable type having at the bottom a cold Serial No. 799,858.

water supply pipc 2 and at the top the hot water discharge plpc 3 which leads to the house or other supplyasystem. The specific construction of the boiler, however, forms no part of my invention, and I have therefore in the present drawing shown a con: ventional form of the type utilizing a gas burner as a heating medium, since the regulator of, my invention is more particularly adapted for use with such a burner or its equivalent.

4 designates the gas burner, which is arranged below the boiler so that the heat therefrom in ascending, will pass into con tact with the boiler and heat the water passing through the same. The burner t may be of any suitable construction and is supplied with gas by the pipe said gas passing through the mixer valve 6, this latter furnishing the requisite quantity of air to pro vide a smokeless heating flame from the burner. The pipe 5 is preferably provided with a shut-off valve 7, and at its lower end is connected to the discharge port of a .valve body 8, the inlet port of which connects with the gas supply pipe 9. Within the valve body 8 there is a gas valve piece 10 which controls the supply of gas to the pipe 5, and is itself automatically operated by a water actuated motor-valve 11, in such a manner that if the pressure of water in the hot water pipe 3 is relieved by the opening ofthe spigots on the house system, the pressure of the waterfrom the street main, in forcing the water through the valve 11 into the boiler will open the gas valve 10 and supply gas to the burner. It will here be noted that the cold water supply pipe 2 connecting with the bottom of the boiler bpdy has its supply end connected with a pipe 12 leading from the street water main, the connection being made through a special 1notor-valve 11, which performs the dual function of a check valve and also a motor for operatingthe gas supply valve 10 which s to supply the gas of the heating medium in accordance with the requirements of the boiler. "With this construction in mind, it will be seen that when the pressure in the boiler accumulates by shutting oil or reducing the flow of water therefrom, the motorvalve 11 operates to close or partly close the gasvalve 10 and thereby shut off or partly shut oil the flow of gas. The supply of gas to the burner, in this manner, may he variation in the how.

I 5 preferably utilized to provide a means for ignition purposes when the gas i: turn and may be permitted to burn constu will bennderstood. The pilot light here shown is controlled by a shut-oh valve i l.

The body ofthe water motor-valve is provided with a valye seat 15, adapted toreccive a check valve 16, the function of which is prevent. the escape of water from the boiler 1 backinto the supply main. This check valve 16 is preferably provided with a downwardly extending cylindrical body ,17 having ports 18 through. which the water may flow when the valve israised-so as to bring the ports above the valve seat l5.v As here shown, the cylindrical body 1? makes a substantially sliding through the valve seat so that may act a piston when the water is flowing into the boiler? The upper or conical forms the check valve 1.6 hen it rests upon the valve seat, during the periods when no water is being drawn from the boiler, l"? desireo, a spring 19 may be employed to assist in closing th valve 16 maintaining it seated when the water cases to flow from the boiler, The valve ody 17 is provided with a downwardly exendinigstezriQO-pas through a stufiing 21 and pro l a, llS lower end with. a 322 which is adaut i e to reciprocat with valve body 17, E be valve body 8 is rovidedith aconical valve seat to ha-seat for the gas valve 10 so that the supply of gas from the pipe 19130 the pipe o may be controlled. The upper part of the body 8, that is, on the inlet side, is provided with a flexible diaphragm 24:, which is preferably of leatheror other suitable flexiblema terial, and has attacoed to the center the stem 25 of the gas valve 10. l he stem 45 25 the present instance extends upward through the diaphragm 2t and also through the bottom of the yoke 22 where it is provided with transverse part 26 which is liftedby-the yoke on its up stroke. vconnection thus formed is substantially a lostniotion one, so that when the gas valve 19 is seated the water n1otor-valve may still move sufficiently toseat itself and act as a check valve. Furthermore, this loose connection between the two valvepieces l7 and 10 enables each of them to seat perfectly upon its 5 own seat, and also prevents any possibility of objectionable friction which might make the device fail to operate automatically.

It will be observed that at all times the water pressure from the pipe 12 is tending to lift the valve 17 of the water motor-valve 11, and thus insures the supply or" water to to pass from the boiler by the pipe messes The pressure of the gas from the pipe 19 is practically balanced by acting simultaneously upon the valve 10 and the diaphragm 2t, and the said valve-10 is therefore only responsive to permit the flow of gas at times when the water is flowing into the boiler. is this way, not. only areeconomical conditions as to the consumption of gas insured, but the construction is such that the pressure of the gas does not materially interfere with the motor action of the water valve. ,l lhile l have shownthese valves and their connections in the form which l-liave found satisfactory-in practice, I do not confine myself to the details, as these may be reasonably modified without departing from the cooperating requirements involved-in my 'invention, It will also be seen that the valve bodies 8 and 11 are securely fastened at 27 to an upright standard 28 extending from the bed nlatcQQ, so that the parts contained w' n the said body are held in proper alinement and relation to each other, and with the boiler and other coni'iections, all of which secured to the same base plate. In this v' the boiler, regulator on asjuncts ma oe placed in position or shifts as a unit in installing it in building, so

that all ofthe operating mechanism, connections and adjustments may be properly mad in the machine shop, thereby leaving nothing but the mere coupling coi'inections with the ga main, street main and house supply sys 1 to he done the time of the installation ln dcscrioing the operation. of the regulating device, it will, be assumed that tbe boiler is full of water, the gas valve 10 closed to cut off the gas supp'lyand the pilot light burning. "Under these conditions, the turning-on of any spigot or spigots in con nection with the pipe 3 willin antly cause the pressure in the boiler to be reduced, so that the superior pressure in the water supply pipe fl2-will operate the water motor- When sufficient hot water has been drawn 05 the water spigot will be closed and the gas supply thereby automatically cut off through the action ofthe motor-valve 11, and the hot water still remaining in the boiler may be stored until drawn 05 for future use, at which time the heating operation will be repeated. At no time can the apparatus operate to generate excessive temperature with the accumulations of steam within the boiler with its consequent objections and dangers.

llurtherniore, the operation of my improved apparatus is economical because it does not reset aeuse any gas except in accordance with the specific requirement of heating.

While I prefer the construction shown,

the details thereof may be modified Without I claim as new and desire to secure by Let ters Patent is 1.
